lie it known that I, EIHIGNE L. KnYEs, a

citizen of the United States, residing at ioston, in the county ofSuttolk and State of Massachusetts, have invented certain lmprovementsin Welt-Butt -'l aeking Machines, of which the following description, ineonnectitm with the accompanying drawings, in a specification. likereference characters on the drawings indicating like parts in theseveral tigures.

This invention relates to machines for use in the manufacture of bootsand shoes as, for example to lasting and tacking machines, and isembodied in a machine for tightening a welted shoe to the last adjacentto the end of the heel seat and fastening it.

Objects of this invention are to increase the speed and etliciency andreduce the labor required to operate some machines heretofore proptsedfor this work, including the machine of my prior application Serial No.2.90529, filed Oct. 28, 1907.

An important feature of this invention consists in the provision ofnovel means for tightening and holding the shoe stock in position to befastened including, if desired, means for locking the tighteningmechanism. This is shown as including oppositely disposed shoe engagingor clamping members, each of which is arranged to engage the shoe at theupper and lower edges of the heel stitlener for forcing the sides ofthis portion of the shoe snugly to the last. The lower portions of theengaging members clamp the sides of the shoe first at a point somedistance below the insole and act upwardly and inwardly to gather thefullness of the upper and force it toward the insole, while the upperportions of the en gaging members are formed to engage in the welt:criase under the end portions of the welt to take up the fullnes in thestock developed by the lower clamping members and to tighten the stockover the last edge by pressure against the welt and the upper and, itmay be, against the stitches of the inseam which said member may beshaped to engage in the crease. The opposed clamps are connected foroperation together by means which is shown as manually actuated and, inone embmliment of the invention. a locking means is providedconvenienttv arranged with relation to the actuator for manipulation inrelation therewith.

Another very important feature of this invention is found in theprovision for prescntation of different portions of the work alternatelyt0 the tacking mechanism. As shown, the work clamping device or holder,formed as above indicated or otherwise, is mounted and preferably guidedrelatively to a tacker for movement to present one tightened side of theshoe in position to be fastened and then to present; the oppositeportion or side of the shoe while the stock continues to be held. ln theillustrated construction, the work holder is guided for transversemovement in the tacking machine. The shoe is yieldingly upheld upon aspindle which is raised in time relation to the tacking operation. Afterthe Work clan'iping device or holder has been actuated to tighten theshoe to the last, the shoe is positioned with one side of its bottom,including the over-worked edge of the upper or the welt, or both, underthe nozzle of the tacker and the treadle is then depressed to raise theshoe tirmly against the nozzle and then to start the tacker. A pluralityof tacks may be driven if desired and then the work is sait'tedlaterally to present the other side of the shoe bottom in position to betacked.

A. further feature of the invention consists in provision for laterallypositioning the movably supported shoe relatively to the tacker for thetacking operation. Preferably stops are employed which are positionedrelatively to the shoe and are aringed to engage the machine as the shoeis moved transversely to determine the distance from the side edge ofthe shoe at which the tacks shall be driven.

The machine is so constructed and arranged that its use requires verylight manual labor and a small degree of skill so that it can betmerat-ed by a boy or other cheap tabor.

These and other features of this invention will be more fully explainedin connection with the detailed description of the machine in which theinvention is illustrated as embodied and will then be pointed out in theclaims.

In the drawings :Figure 1 represents a machine embodying thisinventii'ai in a preferred form; Fig. 2 represents the oscillatirgclamping device in perspective; Fig. i) represents the last; spindle indetail; Fig. it

represents a modified construction covered by my divisional applicationSerial No. (333,469, tiled June 16. loll; Fig. 5 represents inperspective, the clamping device of the modified construction; Fig. (irepresents the presser-foot of the tacking machine and Fig. 7 is asection through the shoe and last in front of the clamping deviceshowing the relative position of the clamps and the tacker when inoperative position.

Referring to Fig. 1 A represents the standard of a tacking machine ofcommon type, a description of which is found in United States Patent No.389.2%, granted September 11, 1888, and need not be given herein exceptin general. 2 is a tack hopper and tack arranging and feeding device, a:one clutch member and (3 is the driving pulley which forms the secondclutch member, 8 is the clutch operating lever, and 10 is a cam whichacts on a lever 12. which is fulcrumed at l-l. On the lever is pivoted alever 16, the left hand arm of which is: forced upward by a spring 18and rests against a block 20 on the clutch lever 8. The block 20 isengaged by a. shoulder on the lever 16 and when this lever is displacedlengthwise to the left by the cam 10 and lever 12, the clutch is thrownout. The cam 10 timed to throw out the clutch just b fore the tack isdriven so that, when the clutch is thrown in by depressing the left handend of the lever 16 so as to disengage the shoulder thereon from theblock 2() the tack will be immediately driven. The lever is depressed bymeans of a spring-pressml dog 22 attached to a. rod 24 leading to lever26 and treadle lever 28. 'hen the treadle is depressed the dog engages aprojection on the lever 16 and depresses it, thus permitting a spring 11to throw the clutch in.

The means whereby the shoe is supported and the parts pressed intoposition to be fastened by tacks from a nozzle 30 are mounted on apivoted support. including the member 42, capable of limited oscillationto bring the opposite sides of the shoe alternately under the tacker.Referring to these parts more in detail a block Ell is rigidly clampedto the standard A. In a groove in the front. face of the, block slides abar 36 which is connected at its lower end by a rod 38 with the treadlelever mechanism and at its upper end has a bolt 40 rigidly securedtherein on which is pivoted for limited oscillation, the support 42 ofthe shoe clamping means. Referring now particularly to Fig. 2, it willbe seen that the bar 36 has beveled edges and slides in correspondingways in the block 3-} so that it cannot be displaced laterally. The headof the bolt 40 is provided with a slot in which in erted a downwardlyextending tongue ll. Opposite. to the lower end of the tongue ll rods 40are threaded through ribs eh") on the support 42 and are provided withthumb lock nuts l8. The support which holds the shoe is thus mounted tooscillate on the bolt all) about a center which preferably issubstantially the center of curvature of the average shoe shank near theheel breast line to an extent determined by the adjustment of the stoprods 46. ,ly this construction the shoe support may be given a sidewisemovement in a curved path corresponding to the average curvature of theshanks of shoes about the pivot. of the support to bring the sides ofthe shoe alternately into operative rein-- tion to the tacker and theshoe presented at a predetermined angular relation to the tacker, sothat the tacks will be driven in a direction inclined in ardly from theedge of the last. Upon the top of the support 122 are bosses 50, 50 onopposite sides and a boss between them. On the bosses 50., 50 arefulcrunied levers 5t, at by tap bolts 56, at). Power is applied to thelevers by a pin and slot connection between the rear ends of the leversand blocks 58 which are moved toward and from the central boss 52 bymeans of a right and left threaded screw 0 which is rotated rapidly bymeans of small. and large gears (32 and (H and a hand wheel ('16 in amanner obvious from inspection of Fig. 2. The middle unthreaded portionof the right and left screw tit) is journaled in the boss and means isprovided for prevent ing longitudinal movement. of the screw therein. Inthe boss above the journal of the screw and at right; angles thereto ismounted the stem 8 of a back rest T0. The stem of the rest slides freelythrough the boss 52 and is normally held forward by a. spring 72.

()n the forward ends of the levers 54 are shoe engaging clamps 74 whichare pivoted to blocks 76 by horizontal pins 78, the blocks being in turnpivoted to the levers it by vertical bolts 80. In this manner limiteduniversal movement is provided for the clamps Tl with respect to thelevers Leaf springs 82 are fastened at one end by the bolts 80 to theunder sides of the blocks ((3 and their free ends engage the lower endsof the clamps Tl to force them toward each other. Springs 84 (Fig. l)are attached to the under side of levers St and to the inner part of theclamps, to keep the clamps in normal position facing inwardly shown. Theinner sides of the clamps are shaped to grasp a shoe about the rearshank portion and have pads 86 of some material which will not injurethe finish of the leather of the shoe. The pads how yet do not extendthe whole length of the clamps but stop short of inwardly projectingportions 88 on the upper ends of the clamps; these rigid portions areformed to enter the well: crease of a welted shoe and serve to force thewelt and adjacent parts firmly together near the point of nailing and toposition or locate the welt butts for the tacks to be inserted therein.As the padded lower ends of the clamping members Tet are pressedinwardly by the springs 82 they engage the upper first at a pointconsiderably below the insole and press and smooth it upwardly andinwardly against the last as they close until finally the rigid upperends 88 of the clamps engage the upper in the welt crease and force itlirmly in over the insole. By this means the upper drawn tightly overthe last and into position to be tacked in place.

In the prior constructions of which I am aware there has been a tendencyfor the welt locating blades to lift the stock and hold it away from thelast bottom at the tacking point. Pressure of the lower ends of thedevices 74 against the side of the shoe insures a downward component ofpressure by the crease engaging ends 88 while said ends are pressinginwardly against the stock of the welt seam, thereby obviating theobjectionable lifting of the stock which accompanies the use of otherconstructions.

To provide for slight movement of the shoe so that it is free to beclamped in position for tacking, the spindle SE) of the jack is pivoted(Fig. 3) in the bifurcated end of a jack rod 90. Below the pivot of thespindle a notch 92 is provided in which is seated, normally, a springpressed pin 941. In this way the spindle is held upright but is capableof being moved to a limited ex tent from side to side. The jack rod 50slides in a sleeve 96 which is pivoted at 98 to the base of the support.To the lower end of the sleeve 96 is pivoted at 99 a jacl; lever 100which is pivoted to the jack rod 90 at 97, a slot in the sleeve 96accommodating the pivot pin. The lever 100 is held in depressed positionwith the rod 90 raised by a pawl 102 engaging a ratchet segmcrn 104formed on the sleeve 96.

In the operation of this form of the machine the last with a welted shoeon it is placed on the spindle and elevated to the proper degree bydepressing the lever 100. The hand wheel (56 is then operated to bringthe clamps 74 simultaneously in toward the shoe which they engage firstat a point remote from the bottom and press the mate ial inward, andtoward the bottom, rocking meantime on the pivots 78 until the rigidfingers 88 engage the upper beneath the welt and tighten the upper andpress the stock down upon the last bottom into position to be tacked.lVhen the shoe stock has been clamped with suflicicnt force in theproper position the support 45 is rocked to one side until one of theships to engages the tongue 14-. This movement will, it the stopl-(S isproperly adjusted, bring the margin of the shoe bottom in properposition under the tacker. The treadle 28 is now depressed to raise thejack so that the shoe is pressed against the nozzle of the tacker and totrip the clutch by depressing the lever 16 through the dog 22 and rod34. Tripping the clutch starts the tacker into action and a tack isdriven to secure the upper in tightened condition and it may also be tofasten the welt butt and the heel stiliener to the insole. The treadleis released during the first tacking operation and the cam 10 throws outthe clutch and stops the machine as it is on the point of drivinganother tack leaving it ready for the next operation which occurs whenthe shoe jack is swung over against the other stop 46 and the pedallever again depressed.

tcferring now to Figs. 4-, 5, (l and 7 in which a somewhat modifiedembodiment of the invention is shown, 150 is a jack rod which isslidingly mounted in a socket block 152 which is loosely pivoted at: 157to the lever 26. Within the block 152 a spring lo t is provided foryieldingly pressing the rod upwardly. Excess movement of the jack aboutthe loose joint 157 is prevented by a bracket 15o which embraces thejack rod and is bolted to the standard of the machine. The jack rod isin two parts connectcd l a collar 138 which is pinned to the lower partof the rod and threaded to the upper part so that the length of the rodmay be adjusted by rotating either part relatively to the other.

The clamping means in this construction comprises spring lingers lot),bolted to levers 1H2, 103, and rigid plates [or which are pivotallymounted on the levers and hence may be disposed at the proper angularposition to clamp the upper to the last. The lingers 100 are prctcrablycovered with noirabrasive material. Lugs lot; on the levers carryadjustable stops 168 to engage the nozzle so of the tacking machine (seeFig. 7). The levers 102, 10; are pivoted at 170 to a block 171 and areprovided with intermeshing toothed segments 1T2 whereby the clampinglingers are made to move simultaneously in opposite directions; thelever 163-) has a handle 171 for operating the clamping fingers andmeans is provided l'or locking the lingers in clamping position. Thisconsists of a plate. 170 pivoted to the lever 162 at one end and at theother provided with a slot 178 through which passes a pin 180 on thelever 103. ()n the pin is pivoted eccentrically at 182 the bifurcatedend of a catch lever 18* which is held in engaging position with theslotted plate 176 by a spring 180, the other end of which is attached toa pin 192 extending from the lever 16?). The lever 1M carries o'llsettherefrom a thumb piece 188 disposed in convenient position to beengaged by the thumb of a hand of the operator while holding the handle174'. By this means the clamp may be readily unlocked. A height gage 190for the shoe is attached to the levers 162 and toil by a screw and holeand by a screw and slot respectively.

The clamping mechanism is attached to the machine standard for lateralsliding movement by the engagement of a T-shaped curved tongue on theblock 171 with a corresponding groove in a plate 200 attached to thestandard the curve of the tongue being taken from the pivot of the jackpost 157 as a center. Springs .202 are attached to pins 201 and to theblock 171 on each side of the machine and tend to hold the block innormal position. The pins 204 also serve as a pivot or hinge tor theplate 200 which moves about this pivot as the clamps are raised by thejack toward the taeker.

In Fig. (3 is shown the nozzle of the tacker detached. As shown theengaging surt'aee is ribbed or corrugated but it may be made smooth, itdesired. The mode of operating this 'lorm ot device is substantially thesame as that of the form previously described and an extended accountthereof will therefore not be necessary.

The shoe is jacked in the usual manner and s 'ung in between the jaws ofthe clamp or holder which is closed thereon by operation of the handleli t. The tingers lot) press the upper and stitlener to the sides ot thelast and then the rigid blocks lttt clamp the upper and heel stitl'enerfirmly and hold it as in Fig. 7. The clamp is then locked by the actionof the spring lot; upon the lever 1st. The shoe is now swungto one sideuntil one of the stops ios engages the nozzle Ill) it the taeker. thecurved tongue on the block lTl, during this movement. sliding in theblock 200. The pedal lever its is now depressed and the tack driven aspreviously described. The operation is then repeated upon the other sideot the shoe.
